At the Muiderzand marina in The Netherlands, Kongsberg customers gathered for a working demonstration of the EM2040 Compact multibeam system on board the survey vessel ‘Havenschap 1’.

The Havenschap 1 is equipped with a moon-pool mounting configuration to accommodate the EM2040C single sonar head together with a dual frequency single beam transducer; a proven concept and easy to install.

The demonstrations took place over different areas including, shallow water with a sandy bottom and also with a muddy bottom, and Kongsberg say the results were all excellent.Results showed just how clean the raw and unprocessed (with filters off) data can be when using the EM2040 Compact.

Due to the high pinging frequency, harbour mooring poles of 20cm diameter were nicely detected even with relatively high vessel speeds. The image shows data taken when entering the marina at 6km/h, at 2.8m depth (notice the rope on first pole).
